This filter is composed of woven fabric alternated with paper, and the whole secured together to form a solid sheet.

It is claimed that this filter is equally adapted for the filtration of wine, cider, spirits, lime-juice and many other viscous or syrupy liquids, and equally at light as at high pressure. Force pump can be used.

Filtering bags are of superior quality and certainly adapted for what are claimed for them. But whether the filter represented in Fig. 26 will answer just as well is a question which depends on its construction. If it is silver lined or nickle plated where those liquids come in contact with the metallic part of the filter, it is all right and a practical contrivance to clarify alcoholic liquids.
